Question about Buick Reatta
I was at the mall today and locked my 1989 Buick Reatta, I'm assuming that someone tripped the anti-theft system. When I returned to my car the security light in the dash was blinking as well as the light indicating the parking lights being on. When attempting to start my car the radio and ac turn on but nothing else. Does anyone know how to bypass the anti-theft system?
The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

The price is forbidding our small income expenses. . .BUT if you can
determine my explanation below that your bypass is compatible with ours?
We, I, my wife and baby, are confined in the seculed place in Hayfork
mountains. . .I am seeking for main stand-alone switcher that turns off
against fuel pump, against inner dome light, against rear trunk lid light,
against auto transmission and against four door lock actuators . . .I
successfully made it run with bypass starter relay and hot wired down to
gas tank pump and it runs well but "service immediately" light stays on..
and auto transmission starts on 3 rd gear that stalls engine, it wont start
on second gear. . .when arrived home on uphill road it wont go up so I
drove it on reverse and finally parked here. . .
I KNOW it is a few steps ahead where stand-alone switcher are. I am going
to follow the dome light's wire down to the place where relay-switchers
are. . or follow gas pump wire that I assume can be very hard way to do. .
but before I go ahead that if you can tell me where those switchers for
A/T, fuel pump,inner lights, doors are located?? in 1998 SL1 ? that would
really save my searching . . . Your tips without having to purchase your
bypassing kit would be greatly appreciated.

I just had this same problem with a '96 . do you have a vats key in your '94? you need to bypass the VATS system. read some of the blogs on this site and it will tell you how to do it. I fixed mine with a $2 resistor from radio shack.

I had that same problem and it took me forever to figure out what was wrong. You are probably using an aftermarket key as was I. The stupid little plastic/metal chip in the shaft of the key is for the security system. Sometimes if you insert the key and turn too fast it sets off the security system. To solve the problem go get another key made from a different key maker, they cost around $15-20. Or, insert the key slowly and turn the ignition slowly. Or go get a good key from the dealer, I've heard it may be ~$50 for this key but it should work the best. FYI I still just use my aftermarket key and just deal with the occasional no start wait 3 min ordeal. Good luck.

take the positive side of the battery off for about 3 seconds and then put it back on to see if this will reset the security code
